Final answer:
The term for when an artwork switches colors, changing the foreground and background in color theory is referred to as 'Color Inversion'. This technique manipulates colors and swaps them with their complementary counterparts on the color wheel, altering visual perception and creating a dramatic effect.
Step-by-step explanation:
In the realm of color theory, the term used when an artwork switches colors, effectively altering the foreground and background, is known as Color Inversion. This technique manipulates color values and shifts the color spectrum to its opposite end. For instance, if an image predominantly uses light, warm tones such as yellows and reds, color inversion would replace these with dark, cool tones like blues and purples. This changes our visual perception and creates a dramatic effect because these inverted colors are known as complementary colors in color theory, positioned directly opposite each other on the color wheel. A prominent example of color inversion can be seen in negative film photography wherein colors are reversed.
